Question 17 5 Point The Supplier Of A Gas Turbine Bearing Housing Declares That The Minimum Number Of Cycles To Failure 1 (500.76 KiB) Viewed 43 times

QUESTION 17 5 point The supplier of a gas turbine bearing housing declares that the minimum number of cycles to failure versus stress (S-N curve) is 65 logo (Nf) = log10 o -0.35 o uts where Nf is the number of cycles to failure at stress level o (MPa) and outs = 420.2 MPa. The component has logged 1000 cycles at 150.6 MPa and 10,000 cycles at 148.9 MPa. Determine the percentage of the component life that has been used. State your answer as a numerical value to one decimal place without the percentage sign, e.g. for 12.3%, write '12.3' and not '12.3 %'. Partial credit is awarded for a reasonable approximation to the correct numerical answer.
